Principles for selecting raw materials in the chemical process technology route: In the preparation and planning of chemical projects, the choice of raw material route is a crucial factor that affects the entire production process; its rationality is directly related to the project’s feasibility, economic viability, and sustainability. The selection of raw material sourcing routes must adhere to three core principles, establishing a scientific basis for decision-making from aspects such as supply security, economic efficiency, and resource utilization. I. Principle of reliability: Chemical production is largely based on continuous processes, and a stable supply of raw materials along with their compliance with quality standards are fundamental prerequisites for normal operation. Fluctuations in the supply of raw materials in terms of quantity and quality not only reduce production efficiency and affect the return on investment, but may even lead to the failure of the project. To ensure the reliability of raw material supply, it is necessary to identify specific supply channels in advance; during the project decision-making stage, a thorough investigation and assessment of the supply capacity of the supplying departments or raw material manufacturers must be carried out ； For large and medium-sized projects, the supply of raw materials should also be incorporated into the material supply planning at the ** or regional level, in order to ensure stability in supply on a macro level. II. The principle of economy: The selection of a raw material route depends not only on the price of the raw materials themselves, but also has cascading effects on various aspects such as product quality, production volume, consumption levels, operating costs, as well as the technical plans for plant construction, site selection, and environmental protection. These factors ultimately influence the investment, costs, and profits of the project. By \"economy\" is meant the overall economic impact resulting from different raw material routes. At the same time, the economic viability of raw material routes is not fixed; it changes over time, depending on location and resource conditions — especially as technological advancements significantly alter the economic value of raw materials. Therefore, when selecting raw materials, it is necessary to take into account the current market prices as well as the trends in market supply and demand, in order to make reasonable predictions regarding price fluctuations. III. The principle of rationality: This principle focuses on the comprehensive utilization of resources, with the aim of enabling limited resources to achieve better economic outcomes. From a technical perspective, promoting the comprehensive utilization of raw materials, achieving \"atomic economy\" in reactions, or giving priority to the use of non-toxic and harmless raw materials can reduce environmental pollution caused by the emission of \"three wastes\", and these are important approaches for developing green chemical processes. At the same time, local or nearby regional resources should be given priority in raw material selection; this not only ensures easy access to these materials but also helps to reduce transportation costs and the volume of goods transported, thus balancing supply efficiency with cost control. These three principles are interrelated and work together; they represent the key factors that must be taken into consideration when selecting raw material routes for chemical projects, thereby helping to achieve comprehensive goals of technical feasibility, economic Reasonableness, and efficient use of resources.
